Abstract

The present invention is a character image generation system (100) for generating outline font based on character information and displaying the outline font on a display with a prescribed number of pixels. The character image generation system (100) subdivides a curve expressed by character outline information corresponding to inputted character information (101, 102), calculates the difference between coordinates at each end of the subdivided curve (103), compares the difference with a predetermined threshold value (104) and sequentially calculates coordinates for each pixel (105), based on this comparison result.
